\[\frac{3}{23} + \frac{9}{23} = \frac{3+9}{23} = \frac{12}{23}\]
\[\frac{32}{33} - \frac{5}{33} = \frac{32-5}{33} = \frac{27}{33} = \frac{9}{11}\]
\[\frac{5}{33} + \frac{4}{9} = \frac{5 \cdot 3}{33 \cdot 3} + \frac{4 \cdot 11}{9 \cdot 11} = \frac{15}{99} + \frac{44}{99} = \frac{15+44}{99} = \frac{59}{99}\]
\[\frac{8}{17} + \frac{15}{17} = \frac{8+15}{17} = \frac{23}{17} = 1\frac{6}{17}\]
\[\frac{9}{10} + \frac{1}{10} = \frac{9+1}{10} = \frac{10}{10} = 1\]
\[\frac{22}{29} + \frac{11}{29} = \frac{22+11}{29} = \frac{33}{29} = 1\frac{4}{29}\]
\[\frac{1}{8} + \frac{3}{8} = \frac{1+3}{8} = \frac{4}{8} = \frac{1}{2}\] кг
\[7\frac{1}{8} - \frac{1}{2} = \frac{7 \cdot 8 + 1}{8} - \frac{1 \cdot 4}{2 \cdot 4} = \frac{57}{8} - \frac{4}{8} = \frac{57-4}{8} = \frac{53}{8} = 6\frac{5}{8}\] кг
Ответ: Маша съела \(\frac{1}{2}\) кг арбуза, осталось \(6\frac{5}{8}\) кг.
